﻿GENERIC 
  REVISION 
  OF 
  THE 
  OPIIIONINI 
  — 
  CUSHMAN 
  445 
  

  

  li'ft 
  in 
  Ophion, 
  but 
  from 
  descriptions 
  of 
  that 
  spocies 
  it 
  is 
  apparent 
  

   that 
  it 
  agrees 
  with 
  the 
  original 
  description 
  of 
  Eremohjlus 
  and 
  can 
  

   stand 
  as 
  the 
  genotype. 
  

  

  Subsequent 
  to 
  its 
  original 
  description 
  Lremotyhis 
  has 
  had 
  three 
  

   somewhat 
  ditferent 
  interpretations. 
  The 
  first, 
  and 
  the 
  one 
  here 
  

   followed, 
  was 
  that 
  of 
  Thomson, 
  with 
  Ophion 
  marginatus 
  Gravenhorst 
  

   as 
  type. 
  Ashmead 
  (lS9t)) 
  gave 
  it 
  a 
  second 
  interpretation 
  when 
  he 
  

   placed 
  in 
  it 
  his 
  E. 
  arctiae, 
  an 
  American 
  species 
  of 
  Enicospilus 
  without 
  

   scleromes; 
  while 
  Kriechbaumer 
  referred 
  to 
  it 
  Ophion 
  undulatus 
  

   Gravenhorst, 
  genotype 
  of 
  AUocamptiis 
  Thomson 
  and 
  Oi/matoneura 
  

   Kriechbaumer 
  on 
  a 
  later 
  page 
  of 
  the 
  same 
  paper 
  in 
  which 
  he 
  had 
  

   erected 
  Cymaioneura 
  for 
  that 
  species. 
  The 
  last 
  two 
  interpretations 
  

   I 
  consider 
  synonymous 
  with 
  Enicospilus 
  Stephens, 
  Mr. 
  Perkins 
  

   writes, 
  "the 
  only 
  species 
  I 
  recognize 
  as 
  belonging 
  to 
  Eremotylus 
  is 
  

   marginatus 
  Grav.," 
  and 
  " 
  Camptoneura 
  curvinervis 
  Kriechbaumer, 
  

   I 
  consider, 
  belongs 
  to 
  a 
  distinct 
  genus." 
  

  

  The 
  following 
  generic 
  description 
  of 
  Eremotylus 
  is 
  compiled 
  from 
  

   those 
  by 
  Thomson 
  and 
  Brauns, 
  with 
  several 
  characters 
  (indicated 
  

   by 
  quotation 
  marks) 
  furnished 
  i)y 
  Mr. 
  Perkins 
  interpolated: 
  

  

  Head: 
  Temples 
  broad; 
  occipital 
  carina 
  distinct; 
  ocelli 
  small, 
  not 
  

   touching 
  eyes; 
  clypeus 
  not 
  separated, 
  apex 
  rounded; 
  mandible 
  stout, 
  

   "not 
  conspicuously 
  twisted," 
  teeth 
  ec[ual. 
  

  

  Thorax: 
  "Pronotal 
  sinus 
  broad"; 
  prepectoral 
  carina 
  above 
  and 
  

   notaulices 
  obsolete; 
  postpectoral 
  carina 
  absent; 
  "speculum 
  sharply 
  

   defined 
  l^clow, 
  strongly 
  transcostate"; 
  mesosternum 
  with 
  a 
  conspicuous 
  

   tubercle 
  on 
  each 
  side 
  at 
  posterior 
  third; 
  scutellum 
  acutely 
  margined; 
  

   propodeum 
  short, 
  basal 
  constriction 
  divided 
  (Perkms 
  says, 
  "sharply 
  

   excavated 
  and 
  undivided"), 
  basal 
  carina 
  acutely 
  elevated 
  in 
  middle, 
  

   apical 
  carina 
  interrupted. 
  Wings 
  with 
  "stigma 
  narrowly 
  lanceolate"; 
  

   radius 
  basally 
  thickened 
  and 
  abruptly 
  curved, 
  "apical 
  abscissa 
  

   evenly 
  curverl"; 
  "fenestra 
  absent"; 
  discocubitus 
  not 
  convergent 
  with 
  

   basal, 
  ramellus 
  absent; 
  brachial 
  cell 
  not 
  narrowed 
  apically, 
  upper 
  

   margin 
  straight; 
  nervulus 
  slightly 
  antefurcal; 
  postnervuhis 
  broken 
  

   far 
  al>ovo 
  middle; 
  a})scisHula 
  strongly 
  curved 
  basally; 
  ncrvellus 
  

   broken 
  below 
  middle, 
  nearly 
  ])erpendicular. 
  

  

  Abdomen: 
  Membrane 
  of 
  tcTgite 
  1 
  reaching 
  spiracle 
  of 
  tergite 
  2; 
  

   tergite 
  2 
  with 
  umbo 
  distinct 
  and 
  "wit!i 
  a 
  deep 
  elongate 
  furrow 
  on 
  

   each 
  side, 
  which 
  is 
  subparallel 
  with 
  the 
  lateral 
  margin 
  and 
  extends 
  to 
  

   about 
  one-half 
  the 
  distance 
  from 
  the 
  base 
  to 
  the 
  spiracle, 
  the 
  spiracle 
  

   at 
  middle 
  of 
  segment." 
  

  

  Such 
  of 
  the 
  key 
  characters 
  as 
  are 
  included 
  in 
  the 
  above 
  description 
  

   indicate 
  that 
  Eremotylus 
  belongs 
  in 
  the 
  Ophion 
  group 
  and 
  probably 
  

   near 
  Boethoneura, 
  new 
  genus.
